Systems and methods provide reliable voice connections dual-connectivity environments, given limitations of available spectrum. A system includes a first wireless station and a second wireless station. The first wireless station provides a shared spectrum of a first frequency band, the shared spectrum including a first spectrum for a first cellular wireless standard and a second spectrum for a second cellular wireless standard. The second wireless station is at least partially within a coverage area of the first wireless station and provides a third spectrum for the second cellular wireless standard. The third spectrum is a millimeter wave (mmWave) spectrum. The first wireless station broadcasts a parameter barring an end device in an idle mode from camping on the second spectrum. The first wireless station or the second wireless station triggers the end device to swap to the second spectrum when a paging request for a voice call is received.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The system of claim 1, wherein the first wireless station is configured to provide a dynamic shared spectrum for the first spectrum, the second spectrum, or both the first spectrum and the second spectrum.
3. The system of claim 1, wherein the first spectrum is used in accordance with a Long Term Evolution (LTE) standard and wherein the second spectrum is used in accordance with a 5G New Radio standard.
4. The system of claim 1, wherein the third spectrum is a millimeter wave (mmWave) spectrum.
5. The system of claim 1, wherein the first wireless station provides for use of a static shared spectrum for a Fourth Generation (4G) standard and a Fifth Generation (5G) standard.
6. The system of claim 1, wherein the switch to the second spectrum changes a primary cell for the end device.
7. The system of claim 1, wherein the first wireless station is configured to bar use of the second spectrum for idle-camping but maintain availability for carrier aggregation or Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA)—5G New Radio (NR) Dual Connectivity (EN-DC) functions.
9. The system of claim 1, wherein the first wireless station includes one of an eNodeB or a gNodeB.
11. The method of claim 10, wherein the first spectrum is used in accordance with a Fourth Generation (4G) wireless standard, and wherein the second spectrum is used in accordance with a Fifth Generation (5G) wireless standard.
12. The method of claim 10, wherein the first wireless station provides a dynamic shared spectrum for the first spectrum, the second spectrum, or both the first spectrum and the second spectrum.
16. The method of claim 10, wherein the end device is an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA)—5G New Radio (NR) Dual Connectivity (EN-DC)-capable device.
17. The method of claim 10, wherein the first wireless station includes one of an eNodeB or a gNodeB.
20. The non-transitory computer-readable medium of claim 18, wherein the first wireless station includes one of an eNodeB or a gNodeB.
